CP2102 USB-to-Serial Bridge

Does this product allow to add a prefix to data processed thru it to USB hub and MS Excel ?

Also when using these —

13.56MHZ/125Khz USB RFID Smart IC/ID Card Key Tag Reader NFC Read Write EM4100 | eBay

can the reader usb be plugged (wired) into CP2102 and CP2102 into usb hub, and then to laptop MS Excel
Thanks
Charles

Hello, Charles.

It is not clear to me what you are trying to ask here. Can you elaborate?

The USB RFID/NFC controller you linked has a USB interface, not a serial interface, so no, you cannot connect the USB RFID/NFC controller to the USB-to-Serial adapter.
